BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a cigarette tube injector, and moreparticularly to a cigarette tube injector which not only can make atight and even injection to have a better quality of cigarettes, butalso has a compact size for enhancing the portability of the cigarettetube injector.

2. Description of Related Arts

The cigarettes consumed by people are normally manufactured by factoriesand are sold in market. A cigarette is a paper wrapped tube stuffed withfinely cut tobacco leaves. Generally the tobacco leaves are cured andprocessed with addictives. There are many tastes and brands ofcigarettes people can select because of the different types of tobaccoleaves, different cure processes and addictives. But still some peoplewant to smoke their own tobaccos.

For those people using their own tobaccos, they have to prepare theirown cigarettes by rolling the paper to wrap their cut tobacco leavesinside. Doing this by hands takes a lot of time, and it is alsodifficult to stuff the tobacco leaves with a uniform and propercompactness. If the tobacco leaves are wrapped too compressed, it isdifficult to smoke; if the tobacco leaves are wrapped too loose, it iseasy to drop the tobacco leaves 40, and get the cigarette extinguished.

Currently there are machines can help people to make cigarettes withtheir own tobaccos, but there are some problems preventing these machinebe used conveniently. Some of these machines still need the user to usehands. For example, a manual crank-type machine can be operated manuallyby filling the tobacco leaves into the crank nozzle such that when thecrank nozzle is inserted into the cigarette paper tube, the tobaccoleaves loaded therein. The advantage of the manual crank-type machine isthat the tobacco leaves will not be shred when the tobacco leaves areloaded in the cigarette paper tube. However, one of the drawbacks of themanual crank-type machine is that the injection is not automatic. Theuser has to use both hands and provides force. It is not convenient touse. Another drawback is that the tobacco leaves cannot be evenly loadedwithin the cigarette paper tube such that compactness of the cigaretteis not uniform.

Some machines are driven by electric power. The tobacco leaves areinjected automatically. But the problem is the size of this kind ofmachine is large. Particularly, the length of this kind of machine hasto be more two times of the length of a cigarette. For example, suchautomatic machine generally has a chamber to contain tobaccos which willbe injected into the cigarette paper tube. In order to fulfill thecigarette paper tube, the volume of the chamber is the same or littlelarger than the cigarette paper tube, and the length of the chamber isthe same or a little longer than the length of the cigarette paper tube.At one end of the chamber is a nozzle which is inserted into one openend of the cigarette paper tube. At the other end of the chamber is apiston to inject the tobaccos inside the chamber into the paper tubethrough the nozzle. The piston is driven by a driving shaft, forexample, as worm shaft. Because the piston will slide through thechamber from one end to another to push the tobacco leaves into thecigarette paper tube, the driving shaft at least has to be the samelength as the length of the chamber. When the tobacco leaves are loadedinto the chamber, the driving shaft has to stay outside the chamber andalign with the chamber longitudinally. Considering the drivingmechanism, the total length of this machine must be longer than thelength of the driving shaft plus the length of the chamber which is atleast two times of the length of a cigarette.

Another type of automatic machine incorporates with a spiral nozzle fordelivering the tobacco leaves into the cigarette paper tube. However,when the spiral nozzle is rotated for delivering the tobacco leaves, thetobacco leaves will be shred into small pieces within the cigarettepaper tube. Therefore, when the cigarette is lightened, the cigaretteash cannot be held properly while smoking. It is a hassle for the smokerto hold the cigarette steadily to prevent the cigarette ash from fallingeverywhere. In other words, if the cigarette ash can be held properly bynot shredding the cigarette leaves in the cigarette paper tube, thesmoker can easily and precisely flick the cigarette ash in the ashtray.

The cigarette tubeinjector comprises a housing 10, an electric motor 20, and a cigarettefilling arrangement 30.

The housing 10 further comprises a tobacco cavity 11 for tobacco leaves40 disposing thereat. The length of the tobacco cavity 11 is around thelength of the cigarette paper tube 50. Referring to FIGS. 2 to 4, alongone longitudinal side of the tobacco cavity 11, the housing 10 comprisesa sliding compartment 13. This sliding compartment 13 locates at onelongitudinal edge of the tobacco cavity 11. The housing 10 alsocomprises a guiding compartment 14. This guiding compartment 14 definesthe height of the tobacco cavity 11 which is slightly smaller than thediameter of the cigarette paper tube 50. A longitudinal length of thehousing 10 is lesser than two cigarette lengths of the cigarette papertube 50.

The tobacco cavity 11 has an opening on top for deposing the tobaccoleaves 40. It also comprises a cutting edge 111 on one side of theopening which is adapted to trim the tobacco leaves 40. The housing 10also has a feeding opening 12 which is communicatively connected withthe tobacco cavity 11. The feeding opening 12 has a tubular holder 121which is coaxially extended from the feeding opening 12. The tubularholder 121 has a sharpened shape so it is easy to be inserted into theopening of a cigarette paper tube 50. When the opening of a cigarettepaper tube 50 encircles the tubular holder 121, the tobacco leaves 40inside the tobacco cavity 11 can be pushed into the cigarette paper tube50. The housing 10 also has a tube retainer 122 transversely extended tobias against the tubular holder 121 by means of spring force to retainthe cigarette paper tube 50 on the tubular holder 121 during injection.

The electric motor 20 is received in the housing 10 to provide drivingpower for tobacco injection. The electric motor 20 also comprises anoutput shaft 21 for generating a rotational power thereat to drive thecigarette filling arrangement 30. In a preferred embodiment, theelectric motor 20 also comprises a gearbox 22 to adjust the rotationalspeed of the output shaft 21 for better performance. The electric motor20 is powered by a power cable 23, or alternatively by a battery 24 tobe portable. In other words, once the battery 24 is charged, thecigarette tube injector is portable to load the loading tobacco leaves40 into a cigarette paper tube 50.

Referring to FIGS. 2 to 6, the cigarette filling arrangement 30 isdriven by the output shaft 21 of the electric motor 20, and is adaptedto automatically feed the tobacco leaves 40 from the tobacco cavity 11to the cigarette paper tube 50 via the feeding opening 12 automatically.The cigarette filling arrangement 30 comprises a tobacco feeder 31, anarc-shaped feeding member 32, a reciprocating unit 33, and a manualactuator 34.

The tobacco feeder 31, which is a feeding crank, is adapted to push thetobacco leaves 40, and it further comprises a driving member 311 whichis slidably supported by the sliding compartment 13. The driving member311 is driven by the reciprocating unit 33 to make a reciprocatingmovement between a first position and a second position. The firstposition is located at one end of the sliding compartment 13 which isalso at the transverse edge of the tobacco cavity 11, and the secondposition is located at the opposite end of the sliding compartment 13which is also at the other transverse edge of the tobacco cavity 11. Thesecond position, is also where the feeding opening 12 locates. Becausethe sliding compartment 13 is at one longitudinal edge of the tobaccocavity 11, the driving member 311 is guided and supported by the slidingcompartment 13 to slide between the first position and the secondposition back and forth linearly along the longitudinal direction of thetobacco cavity 11. The longitudinal direction is also the injectiondirection.

Referring to FIG. 4, the driving member 311 further comprises a frontpusher wall 312. The front pusher wall 312 has a round flat surfacefacing the feeding opening 12 at the second position. When the drivingmember 311 is moving from the first position to the second position, thefront pusher wall 312 can push the tobacco leaves 40 towards the feedingopening 12 without shredding the tobacco leaves 40. The diameter of thefront pusher wall 312 is the same as the height of the tobacco cavity11. The driving member 311 also comprises an arc-shaped retention member313. Referring to FIG. 4, the retention member 313 is extended from acircumferential side of the front pusher wall 312 towards the feedingopening 12 along the injection direction. The arc-shape of the retentionmember 313 is in a semicircular shape. The diameter of the outer wall ofthe retention member 313 is the same as the front pusher wall 312. Thelength of the retention member 313 is the same as the length of thesliding compartment 13. The inner wall of the retention member 313 canretain the tobacco leaves 40 within the tobacco cavity 11, and when thedriving member 311 is moving to the second position, the retentionmember 313 will pass through the feeding opening 12, and enter into thecigarette paper tube 50 with the tobacco leaves 40. It is worthmentioning, the arc-shaped retention member 313 has a small thickness soit will not take much tobacco space inside the cigarette paper tube 50.

It is worth mentioning, when the driving member 31 is at the firstposition, referring to FIG. 5, the whole length of the cigarette tubeinjector is a little longer than the length of a cigarette but lesserthan twice of the length of a cigarette.

Referring to FIGS. 2 to 6, a portion of the driving member 311 is extendout of the sliding compartment 13, and is mechanically connected withthe reciprocating unit 33. The reciprocating unit 33 is adapted totransmit a rotational power of the output shaft 21 to a sliding movementof the driving member 311 of the tobacco feeder 31. The reciprocatingunit 33 comprises a transmission wheel 331 which is coaxially coupledwith the output shaft 21 of the electric motor 20. So the output shaft21 can drive the transmission wheel 331 to rotate. The transmissionwheel 331 also comprises an eccentric shaft 3311 which is located on theedge of the transmission wheel 331.

Referring to FIGS. 5 and 6, the reciprocating unit 33 also comprises aconnecting arm 332, and a transmission arm 333. The connecting arm 332is rotatably connected with the driving member 311 and the transmissionarm 333 respectively through two pivots. The transmission arm 333 islocated over the transmission wheel 331, and has one end pivotallyconnected with the housing 10, and the other end pivotally connectedwith the connecting arm 332. The transmission arm 333 also has atransmitting slot 334 which is slidably coupled with the eccentric shaft3311. When the transmission wheel 331 is driven by the output shaft 21to rotate, the eccentric shaft 3311 will drive the transmission arm 333to swing reciprocatingly through the eccentric shaft 3311 and thetransmission slot. Then the transmission arm 333 will drive the drivingmember 311 to move along the sliding compartment 13 to move linearly. Inthis manner, the rotating movement of the output shaft 21 is transmittedinto a linear movement of the driving member 311 between the firstposition and the second position.

Referring to FIGS. 2 and 3, the arc-shaped feeding member 32 is adaptedto push the tobacco leaves 40 towards the arc-shaped retention member313 and to form a tobacco cylinder, so the front pusher wall 312 of thedriving member 311 can push the tobacco cylinder into the cigarettepaper tube 50. The feeding member 32 is slidably supported by theguiding compartment 14. The height of the feeding member 32 is the sameas the height of the tobacco cavity 11 which is defined by the guidingcompartment 14. The feeding member 32 is also driven by the manualactuator 34 to slide along the guiding compartment 14 in a directionperpendicular to the injection direction.

The arc-shaped feeding member 32 has a feeding wall 321 facing thearc-shaped retention member 313 of the tobacco feeder. The feeding wall321 is also in a semicircular shape which is matched with the retentionwall. When the feeding member 32 is push to the driving member 311 ofthe tobacco feeder, the feeding wall 321 of the feeding member 32 andthe retention member 313 of the driving member 311 will be couplededge-by-edge to form a tubular chamber 35. The tobacco leaves 40 insidethe tubular chamber 35 is formed into a tobacco cylinder which will bepushed into the cigarette paper tube 50 by the front pusher wall 312 andthe retention member 313 of the driving member 311. This tubular chamber35 is coaxially aligned with the feeding opening 12.

It is worth mentioning, the diameter of the feeding wall 321 is the sameas the diameter of the front pusher wall 312, so the front pusher wall312 can slide within the feeding wall 321 along the injection directionto push all the tobacco leaves 40 in the tubular chamber 35.Accordingly, the tobacco leaves 40 will not be shredded into pieces whenthe feeding member 32 is slid to couple with the retention member 313.In addition, when feeding member 32 is slid to couple with the retentionmember 313, the tobacco leaves 40 will have a uniform compactness withinthe tubular chamber 35. In other words, the tobacco leaves 40 are loadedwithin the hollow cigarette paper tube with a uniform and propercompactness by the present invention.

The edge of the feeding wall 321 is sharp. Also, the opening of thetobacco cavity 11 has a sharp cutting edge 111. So when the feedingmember 32 is slid to couple with the retention member 313, the sharpcutting edge 111 will trim the tobacco leaves 40.

The manual actuator 34 is for the user to push the feeding member 32towards the driving member 311 manually. It further comprises a handlemember 341 and a pusher unit 342. The handle member 341 is pivotallycoupled with the housing 10. The pusher unit 342 is pivotally connectedwith the handle member 341 at one end, and is pivotally connected withthe feeding member 32 at the other end. So when the user presses thehandle member 341 downward, the handle member 341 drives the feedingmember 32 to slide towards the driving member 311 of the tobacco feeder31 though the pusher unit 342. When doing this, the feeding member 32can push the tobacco leaves 40 disposed inside the tobacco cavity 11towards the driving member 311 and form a tobacco cylinder.

The cigarette tube injector also comprises a start button 15 and acontrol circuit 16. During operation, the driving member 311 isinitially at the first position. The user first load the hollowcigarette paper tube 50 onto the tubular holder 121, then disposetobacco leaves 40 into the tobacco cavity 11. By pressing the handlemember 341, the user can pushes the tobacco leaves 40 towards thedriving member 341 of the tobacco feeder 34 through the feeding member32 to form a tobacco cylinder. Then the user press the start button 15to start the electric motor 20 to rotate the transmission wheel 331 viathe output shaft 21. The control circuit 16 controls the electric motor20 to rotate the transmission wheel 331 only one revolution. In apreferred embodiment, the control circuit is a contact sensor, when thetransmission arm 333 is driven back by the transmission wheel 331 afterinjecting the tobacco leaves 40, the transmission arm 333 willdisconnect the contract sensor, then the electric motor will be shutdown. In this way the driving member 341 is driven to slide from thefirst position to the second position to push the tobacco leaves 40 intothe cigarette paper tube 50, and then withdrawn from the second positionto the first position, and stopped there waiting for next injection.

As shown in FIG. 7, the cigarette tube injector, as a modification ofthe preferred embodiment, further comprises a cigarette tray 60extending from the bottom of the housing 10 where the feeding opening 12is located such that the cigarette tray 60 is positioned beneath thetubular holder 121 for receiving the injected cigarette paper tubes 50.In a preferred embodiment, the cigarette tray 60 is detachably attachedon the housing 10 such that the cigarette tray 60 can be detached fromthe housing 10 when the cigarette tube injector is not in use so as toenhance the portability of the present invention. It is appreciated thatthe cigarette tray 60 can be slidably engaged with the housing 10 suchthat the cigarette tray 60 can be slid into the housing 10 for storageor can be slid out from the housing 10.

As shown in FIGS. 7 and 8, the cigarette tube injector may furthercomprise a position sensor 17, as an optional accessory, for detectingthe corresponding position of the manual actuator 34. Accordingly, theposition sensor 17 is provided on the top side of the housing 10 at aposition adjacent to the handle member 341 and is arranged in such amanner that when the handle member 341 is pivotally moved to drive thefeeding member 32 for pushing the tobacco leaves 40 towards the drivingmember 311, the position sensor 17 is activated to start the electricmotor 20. In other words, the position sensor 17 is electrically linkedto the control circuit 16 to activate the electric motor 20 such thatthe position sensor 17 functions as the start button 15 to automaticallyoperate the cigarette filling arrangement 30. Preferably, the positionsensor 17 is an optic sensor or a contact sensor to detect the positionof the handle member 341. Therefore, the user is able to automaticallyoperate the cigarette tube injector through the position sensor 17instead of manually pressing the start button 15 to activate theelectric motor 20.

A reset control 18 is further provided to operatively link to thecigarette filling arrangement 30 and to electrically link to the controlcircuit 16, wherein the reset control 18 can be a reset button providedat the top side of the housing 10. Accordingly, the reset control 18 isarranged to reset the initial status of the electric motor 20 when thetobacco feeder 31 is stuck or stopped during the operation. Moreparticularly, when the driving member 311 is driven by the reciprocatingunit 33 and is stuck between the first position and the second position,the reset control 18 is actuated to force the electric motor 20 to drivethe eccentric shaft 3311 in one complete revolution so as to move theeccentric shaft 3311 back to its initial position. Therefore, thedriving member 311 will return back to its original position.

In addition, the reset control 18 further operatively links to theposition sensor 17 for ensuring the operation of the cigarette fillingarrangement 30 in a safety manner. As it is mentioned above, theposition sensor 17 is used for activating the electric motor 20 when thehandle member 341 is pivotally and downwardly moved to drive the feedingmember 32 for pushing the tobacco leaves 40 towards the driving member311. Accordingly, when the handle member 341 is pivotally and upwardlymoved during the operation of the feeding member 32, the position sensor17 will detect the operation as a false operation. Therefore, theposition sensor 17 will send signal to the reset control 18 through thecontrol circuit 16 to deactivate the electric motor 20 and to force theelectric motor 20 to drive the eccentric shaft 3311 in one completerevolution.

Accordingly, the crank type cigarette tube injector of the presentinvention not only can make a tight and even injection to have a betterquality of cigarettes, but also has a reduce dimension and improvedportability. The length of the cigarette tube injector is less than twotimes of the length of a cigarette.
